Oxycarbenes have emerged as useful intermediates in synthetic chemistry. Compared to the
widely studied oxycarbene metal complexes bearing Group 6 metals, the synthetic and …

Acylsilanes have been utilized in various transformations for the synthesis of functionalized
organosilicon derivatives due to their importance in medicinal and materials science. This …

Fluorinated fused rings are challenging to construct from simple starting materials. Herein,
we report the first photocatalyzed cascade reactions of readily available cyclopropanols and …

Stereoselective cyclopropanation reaction of alkenes is usually achieved by metal
complexes via singlet‐metal‐carbene intermediates. However, previous transition‐metal …

Although the synthesis of common cyclopropenes has been well studied, the access to
cyclopropenols is rather limited. Herein, we report the first synthesis of α‐trifluoromethylated …

The transition metal‐catalyzed cross‐coupling reaction with Fischer metal carbene
intermediates bearing an electron‐rich alkoxyl or siloxyl group remains a big challenge due …

Acylsilanes are emerging bench-stable reagents for the generation of electron-rich
oxycarbenes that are difficult to access with unstable diazo compounds. Herein, we report a …

Visible light induced singlet nucleophilic carbenes undergo rapid [2+ 1]-cycloaddition with
tethered olefins to afford unique bicyclo [3.1. 0] hexane and bicyclo [4.1. 0] heptane …

Light‐mediated coupling of acylsilanes with indoles is reported. This photo click reaction
occurs under mild conditions (415 nm) mostly in quantitative yield and provides stable …

Herein, we report the first catalytic one-step synthesis of cyclopropenium cations (CPCs)
with readily available alkynes and hypervalent iodine reagents as carbyne sources. Key to …
